That is not strictly speaking true. There have been no long term studies for the most recent mRNA vaccines, but mRNA technology has been in development for many years with much of the effort going into studies of human safety. This long period of development and testing is how the method of packaging the mRNA in a precisely engineered blob of fat came about.

Have there been any long term human trials of mRNA vaccines?

What do you mean?
We can't know what the long term side effects of drugs are until we have long term data.
Even with long term data showing significant negative side effects of drugs, we often dont understand the "mechanism"
